Hi, I have an MPB13 with a 256GB SSD that I'm backing up to an external drive and to a Linux server using Time Machine. The server used to have just a bit more space than the SSD, around 270GB. I just increased that space to 480GB. I wiped the old backup (still have that historical data on the external hard drive anyway) and started a new backup. I interrupted it immediately after the start to increase the band size (see this article). Then I restarted the backup. It finished successfully, but Time Machine showed a backup disk size of around 270GB. That backup disk had around 59.9GB free. I opened the sparsebundle in Disk Utility and increased the size to 480GB. Disk Utility did this and it shows that the Time Machine partition has more than half of the space free. However, Time Machine now shows 59.9GB of 480GB available. So it's taken the free space and kept it. I've tried plenty of things: using hdiutil to change the sparsebundle size, deleting the whole thing and starting again, nothing helps. I've reconfigured the Linux server to make sure that everything is correct. But Time Machine always starts out with the same size as the disk used to be before the resize. And if I resize it manually, the free space stays identical, despite the fact that the disk space has gone up. Any idea? Peter.
